The photoproduction of \(K\Lambda ^\ast \) , with \(\Lambda ^\ast = \Lambda (1405)\) , \(\Lambda (1520)\) , \(\Lambda (1670)\) , or \(\Lambda (1690)\) , is suitable to study nucleon resonances with sizable hidden \(s\bar{s}\)  components in a relatively less-explored higher energy region due to the much higher reaction thresholds of these channels. Besides, the \(s\) -channel isospin \(I=3/2\)  \(\Delta \)  and \(\Delta ^\ast \)  exchanges are forbidden to contribute in the \(K \Lambda ^\ast \)  photoproduction reactions, which simplifies the reaction mechanisms and facilitates the extraction of the information on the isospin \(I=1/2\)  nucleon resonances. Compared with the photoproduction of \(K\Lambda \)  which has been widely studied in various approaches, e.g. chiral perturbation theory [1]}, isobar models [2]}, [3]}, [4]}, \(K\) -matrix approaches [5]}, [6]}, [7]}, and dynamical coupled-channels models [8]}, [9]}, the photoproduction of \(K \Lambda ^\ast \)  has also the advantage that it may couple weekly to \(\pi N\)  and \(\eta N\)  channels due to its much higher threshold, leading to a much clearer background in isolating the complicated resonance contributions. In literature, intensive experimental and theoretical analyses have been devoted to the investigations of the \(K \Lambda ^\ast \)  photoproduction reactions.
